Chip

or Chips.

A carpenter is known by his chips.

A man is known to be a carpenter by the chips in his workshop, so
the profession or taste of other men may be known by their manners or
mode of speech. There is a broadcloth slang as well as a corduroy
slang; a military, naval, school, and university slang.

Such carpenters, such chips.

As the workman, so his work will be.

Brother Chip.

Properly a brother carpenter, but in its extended meaning applied
to anyone of the same vocation as ourselves. (Es nostræ fasciæ;
Petronius.)
